There is a strong correlation between ASVAB percentile scores and IQ levels, as both assessments measure cognitive abilities and problem-solving skills. Generally, individuals with higher IQ levels tend to score higher on the ASVAB, resulting in higher percentile rankings. However, it is important to note that the ASVAB is specifically designed to assess skills relevant to military service, so it may not fully capture all aspects of intelligence measured by traditional IQ tests.
20th percentile = 16th smallest value 60th percentile = 48th smallest value.
The ASVAB scores and IQ levels are related, but not the same. The ASVAB measures specific skills and knowledge needed for military jobs, while IQ tests measure general cognitive abilities. Generally, higher IQ levels may correlate with higher ASVAB scores, but they are not directly interchangeable.
You can't do this without knowing the distribution of scores.
For a complete definition of Percentile see the related link. A percentile is the value of a variable below which a certain percent of observations fallThe 90th percentile is typically the point at which 10 percent of the highest scores fall.If you assume that scores are out of 40, and that they are evenly distributed (an unlikely event in real life), then the 90th percentile is all scores above 36.

The percentile rank of a score is the percentage of scores in its frequency distribution that are lower than it. For example, a test score that is greater than 75% of the scores of people taking the test is said to be at the 75th percentile.Percentile ranks are commonly used to clarify the interpretation of scores on standardized tests. For the test theory, the percentile rank of a raw score is interpreted as the percentages of examinees in the norm group who scored below the score of interest.[1]Percentile ranks (PRs or "percentiles") are often normally distributed ("bell-shaped") while normal curve equivalents (NCEs) are uniform and rectangular in shape. Percentile ranks are not on an equal-interval scale; that is, the difference between any two scores is not the same between any other two scores whose difference in percentile ranks is the same. For example, 50 − 25 = 25 is not the same distance as 60 − 35 = 25 because of the bell-curve shape of the distribution. Some percentile ranks are closer to some than others. Percentile rank 30 is closer on the bell curve to 40 than it is to 20.The mathematical formula iswhere cfℓ is the cumulative frequency for all scores lower than the score of interest, ƒi is the frequency of the score of interest, and N is the number of examinees in the sample. If the distribution is normallydistributed, the percentile rank can be inferred from the standard score.
